SEGTONAL SQUARE.

Specification of Letters Patent.

Application filed January 21, 3.914. Serial No. 813,506.

T0 all iu/zom it may concern Be it known that I, GEORGE H. Gouenu, a citizen of the United States, residing at Charlotte, in the county of Monroe and State of lNew York, have invented new and useful improvements in Sectional Squares, of which the following is a specification.

rlfhe invention relates to tools, and more particularly to the class of sectional squares for carpenters use.

rlhe primary object of the invention is the provision of a square wherein it is made of sections separable to permit the use thereof as a try-square and as a straight rule.

Another object of the invention is the provision of a square of this character wherein the parts when united are assembled in a novel manner and held fast to avoid accidental separation thereof when in use.

A further object of the invention is the provision of a square of this character which is extremely simple in construction, strong, durable, and inexpensive in manufacture.

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereunto appended.

n the drawing F igure 1 is a top plan view of a square constructed in accordance with the invention. Fig. 2 is a top plan view of one section removed. Fig. 3 is a similar view of the other section removed. Fig. i is a sectional view on the line 4 4 of Fig. l. Fig. 5 is a sectional view on the line 5-5 of Fig. l. Fig. 6 is a fragmentary sectional view on the line 6 6 of Fig. 4.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, the square comprises a try-square section 5 preferably formed from flat metal, and a pair of straight sections 6 and 7 respectively, which may be of any desirable length, and are preferably formed from metal, although these sections 5, 6 and 7 can be made from anv other suitable material.

rlhe sections 5 and 6 in one face thereof are milled out to form seats 8 of a depth corresponding to the thickness of the section 5, and also are of a width and length corresponding to the branches of the section 5 so as to snugly receive the same. The sec tion 6 has its seat 8 extended at right angles through one longer edge thereof for communication with the seat 8 in the section 7 when the said sections G and 7 are positioned at right angles to each other as shown in Fig. l of the drawing, and are fastened to the section 5 in a manner presently described.

Mounted for sliding movement in the sections 6 and 7 at the meeting ends thereof and rising from the seats 8 therein are headed pins 9, while formed in the section 5 are substantially key-hole shaped slots 10, through the larger end of which are adapted to pass the heads of the pins 9 so that the latter will engage the narrow portions of the slots l0 when the section 5 is being joined to the sections 6 and 7, the ends of the section being formed with pairs of sockets l1 for receiving retaining pins l2 fixed in the sections 6 and 7 to project into the seats 8 at the closed end walls thereof so that the section 5 will be firmly held in the seats when joined to the sections 6 and 7 as shown in Fig. 1 of the drawing.

lt will be noted that when the sections 6 and 7 are separated and disengaged from the section 5 they may be used as rules, while the section 5 can be used as a trysquare. It is of course to be understood that the sections 6 and 7 have printed or other wise marked thereon suitable scales for measuring purposes. It will be noted that the sections 6 and 7 are formed with elongated slots 13 in which move the headed pins 9 for permitting the convenient fastening and unfastening of the parts of the device.

From the foregoing it is thought that the construction of mv invention will be clearly understood, and therefore a more extended explanation has been omitted.

Vlhat is claimed is:

1. A tool of the class described compris- Ving a try-square section, a pair of separable sections of considerably greater length than the limbs of the try-squaresection, one end of one separable section adapted to abut one longer edge of the other separable section at one end thereof, each separable section having a seat closed at one end, the seats in the said sections merging into each other on the abutment of the said sections and adapted to receive the try-square section, headed members mounted in the separable sections and engageable in the try-square section, and

retaining pins projecting from the closed end oi' each seat for engaging in the corresponding end of the try-square section to hold the same in the seats When the headed members are engaged with the said trysquare section.

2. A tool of the Class described eoinprising a try-square section having key-h0leshaped slots, a pair of separable sections each having a seat With one closed end for receiving the try-square section, headed pins on the separable sections and respectively engageable in the key-hole-shaped slots, and

retaining pins projecting .from the closed end of each seat for engaging in the corresponding end of the try-square section to hold the saine in the seats When the headed pins are engaged in the slots in the latter section.

In testimony whereof I affix my signature in presence of two Witnesses.
